[A]: Connector “E52” (viewed from harness side) 3. Junction block assembly 8. Individual circuit fuse box No.1
[B]: Connector “E49” (viewed from harness side) 4. Fuse 9. Torque sensor signal (sub) circuit
[C]: Connector “E53” (viewed from harness side) 5. P/S control module 10. Torque sensor signal (main) circuit
1. Main fuse box 6. Torque sensor
2. Ignition switch 7. Torque sensor amplifier
DTC detecting condition Trouble area
Voltage difference between torque sensor main signal and
sub signal is more than 0.6 V for 1 second continuously
(1 driving cycle detection logic)
• Torque sensor signal circuit
• Torque sensor
• P/S control module
Step Action Yes No
1 Was “EPS System Check” performed? Go to Step 2. Go to “EPS System
Check”.
2 DTC check
Is DTC C1114 and/or DTC C1119 indicated together?
Go to applicable diag.
flow.
Go to Step 3.
3 Torque sensor signal (sub) circuit check
1) Check for P/S control module connector (“E52”) for
proper connection.
2) With ignition switch turned OFF, disconnect torque
sensor connector.
3) Check for voltage between “E53-7” (“BLU” wire) terminal
and body ground with ignition switch ON.
Is it about 5 V?
Go to Step 4. Go to Step 7.
